The Ni80.2Fe14.1Si0.2Mn0.4Mo5.1 sandwiched films are prepared on the magnetostrictive (Tb0.27Dy0.73)0.3Fe0.7 film substrate. Due to magnetostrictive stress effect on magnetic anisotropy which is believed to be critical for the giant magneto-impedance (GMI) effect, the GMI ratio is seen to increase sharply in the magnetic fields. The GMI effect also increases when the samples are annealed at 280℃. But the GMI ratio is still less than that of the as-deposited films.
